Waterproof and explosion-proof large boiler hearth maintenance lifting platform

Abstract

The invention provides a waterproof and explosion-proof large boiler hearth maintenance lifting platform, and relates to the technical field of boiler maintenance. The maintenance lifting platform comprises a mounting frame made of stainless steel materials, the mounting frame comprises cross beams and sliding arms, the cross beams and the sliding arms are connected in a cross assembly manner, and supporting plates are laid between the sliding arms and / or between the cross beams; and a lifting mechanism is arranged on the mounting frame and pulls the mounting frame up and down through a pulling rope arranged at the top of a hearth. According to the waterproof and explosion-proof large boiler hearth maintenance lifting platform, the height of the mounting frame is determined according to needs, maintenance personnel are prevented from climbing up and down ceaselessly during inspection and measurement, the labor intensity of the maintenance personnel is reduced, and the maintenance efficiency is improved; and meanwhile, the cross beams and the sliding arms are connected in an assembled manner, and the defects of long time consumption and high cost for erecting and disassembling a steel pipe frame are overcome.

Description

technical field [0001] The invention relates to the technical field of boiler maintenance, in particular to a waterproof and explosion-proof large boiler furnace maintenance lifting platform. Background technique [0002] Due to the heating surfaces of the water wall, water cooling screen, superheater and burner in the boiler furnace, there are errors in the design, manufacture and installation process, and the working environment is very harsh during the operation of the boiler furnace. Working under high pressure and high load conditions, it has to withstand the test of oxidation and vulcanization, as well as the erosion and wear of dust in the flue gas. Over time, the wall thickness becomes thinner and the mechanical properties decrease, which in turn leads to the bursting of the boiler tube. At the same time, according to Article 28 of the "Special Equipment Safety Supervision Regulations" of the State Council: power plant boilers need to be inspected regularly. It is i...

Problems solved by technology

[0007] In view of this, the object of the present invention is to provide a waterproof and explosion-proof large-scale boiler furnace maintenance lifting platform to solve the problem of using a steel pipe frame for boiler furnace maintenance in the prior art. There are many unsafe factors such as falling from high places and being injured by heavy objects when building and dismantling the shelf. In particular, maintenance personnel need to climb up and down continuously when inspecting and measuring, which not only increases labor intensity virtually, but also is a technology with low maintenance efficiency. question
